Bridging from Hex to DS3 or DS4

I'm trying to create a prop with morphs that would work in DS3 or DS4. So far, I've been able to use the bridge in Hex to get the model into DS4.5, but there is no option that comes up to activate the bridge to DS3. Am I missing something?

Solution - both versions of Daz have to be installed on the same drive. Sometimes double checking the obvious helps :/
